Abstract:This study aims to identify the dominant error patterns of students in geometry learning based on Newman's Error Analysis (NEA) and to examine their implications for readiness to understand Non-Euclidean Geometry. The method…
thod employed is a Systematic Literature Review (SLR) of 10 empirical articles published between 2019 and 2026. Data were extracted based on the five stages of NEA — reading, comprehension, transformation, process skill, and encoding — and subsequently analyzed through narrative synthesis, percentage comparison, and descriptive effect size. The results indicate that comprehension errors and encoding errors are the most dominant categories, with the highest percentages of 56.92% and 50%, respectively, followed by transformation errors, which consistently fall within a moderate effect range (20–40%), while reading errors and process skill errors are classified as low. The primary causes of errors include weak understanding of geometric concepts, inability in spatial visualization, limited mathematical language, and lack of procedural precision. The findings contribute as a diagnostic foundation for designing more effective geometry learning, while simultaneously serving as a conceptual bridge toward higher-level geometry
Abstract:Dunia digital yang terus berkembang menyoroti pentingnya desain antarmuka pengguna (UI) dan pengalaman pengguna (UX). Namun, kurikulum di Sekolah Menengah Kejuruan (SMK) sering kali tidak memadai dalam menangani masalah…
kritis ini. Kegiatan pengabdian masyarakat ini bertujuan untuk membekali siswa SMK, khususnya di SMK Negeri 1 Air Joman dengan keterampilan desain UI/UX melalui instruksi yang berfokus pada praktik. Kami mulai dengan menentukan kebutuhan siswa, kemudian kami membahas prinsip-prinsip desain UI/UX, diikuti dengan proses pembuatan Mockup UI dan prototype menggunakan Figma, dan diakhiri dengan mereview hasil desain dari proyek mereka. Kami menggunakan pre-test, post-test, observasi praktis, dan kuesioner kepuasan peserta untuk mengukur keberhasilan. Akibatnya, nilai rata-rata peserta meningkat sebesar 70%, dan hasilnya menunjukkan bahwa para siswa puas dengan materi dan metode pengajaran. Pelatihan ini meningkatkan pemahaman konseptual siswa, kecakapan teknis, dan kemampuan untuk menghadapi tantangan di tempat kerja kreatif digital. Ini adalah pernyataan sederhana bahwa pendekatan pembelajaran praktis sangat efektif dalam dalam mengasah kemampuan vokasional di bidang desain digital.

lection methods used by the author are as follows: Documents or References Data collection through written and electronic documents from PT. Sumber Bumi Sawit Jadi Jaya. Field Observation. The method is carried out by direct observation in the company environment. Literature Review. In addition to field observations, data is also taken from several literatures related to this report. The location of the field work practice was held at PT Sumber Bumi Sawit Jadi Jaya which is located on Jalan Besar Mandoge-Kisaran. And the field work practice lasted for 1 month. Starting from September 1st – October 1st, 2023. The conclusions obtained from the results of the practical work are as follows: PT. Sumber Bumi Sawit Jadi Jaya is a factory that processes fresh oil palm fruit bunches into CPO and palm kernel. The processing capacity at PT. Sumber Bumi Sawit Jadi Jaya is 30 Tons of FFB / Hour The organizational structure at PT. Sumber Bumi Sawit Jadi Jaya is a functional organizational structure. The results of processing the percentage of cardiovascular load obtained that all boiler workers needed repairs, and the workload category of the four workers was influenced by age factors
Abstract:This study aims to examine the application of the High-Low method, Scatterplot, and Least Squares in cost analysis, particularly in separating fixed and variable cost behavior. The research uses a library research approach…
ch by collecting and reviewing literature from textbooks, journals, and official publications related to cost estimation and cost behavior modeling. The findings indicate that the High-Low method is simple because it uses only the highest and lowest activity levels, but its accuracy is limited due to reliance on extreme data points. The Scatterplot method provides a visual representation of the relationship between cost and activity, helping identify patterns and potential outliers; however, its results may vary due to subjective judgment in determining the cost line. Meanwhile, the Least Squares method is considered the most accurate because it utilizes all available data to produce the best-fit regression line, although it requires more complex calculations and statistical understanding. Overall, the selection of the most suitable method depends on the objective of the analysis, data availability, and the level of accuracy required
Abstract:Central Java–West Java border communities live in a multicultural environment where Javanese and Sundanese cultures meet, forming distinctive multilingual communication practices. The use of Javanese, Sundanese, and Indonesian…
donesian in everyday life functions not only as a means of communication, but also as a representation of the community's social identity. This study aims to analyze the multilingual communication practices of Central Java–West Java border communities and to explain the role of language in representing community social identity. The study uses a descriptive qualitative approach with a literature review method supported by social-contextual reflection. Data were obtained from various scientific sources discussing multilingual communication, social identity, intercultural communication, bilingualism, and multilingualism. The analysis was carried out through the stages of data reduction, theme categorization, meaning interpretation, and conclusion drawing. The findings show that border communities flexibly use Javanese, Sundanese, and Indonesian according to the context of interaction, social relations, and communication needs. The practices of code switching and code mixing are important parts of daily communication as forms of social and cultural adaptation. In addition, language use functions as a symbol of cultural identity, a means of identity negotiation, and a mechanism of social integration in a multicultural environment. The findings affirm that multilingual communication is a representation of dynamic social identity and reflects the ability of border communities to maintain social harmony amid cultural diversity.
Abstract:This study aims to review the Frugal Living Lifestyle of Millennial Couples in Aceh Tamiang. It can be concluded that making collective spending decisions is crucial for family financial stability and achieving long-term…
goals. By involving all family members in planning, budget allocation, and regular evaluation, each expenditure can be more focused, priorities become clear, and financial responsibility becomes more evenly distributed. In addition to financial benefits, this habit also instills the values of cooperation, communication, and discipline in all family members, including children, thus establishing a healthy financial culture and strengthening family relationships.
Abstract:Computer Vision merupakan sebuah sistem otomatis yang digunakan untuk melakukan analisa citra dan video oleh komputer untuk memperoleh informasi dan pemahaman dari suatu obyek. Computer Vision merupakan kemampuan dari sebuah…
buah mesin atau computer dalam melihat atau mengenali sebuah citra dengan sama atau bahkan dapat melebihi kemampuan pengelihatan manusia asli. Salah satu metode yang digunakan dalam computer vision adalah gabor wavelet. Metode gabor wavelet merupakan salah satu metode yang mampu melakukan proses identifikasi wajah secara real time dan juga mampu melakukan tugas-tugas yang membutuhkan pencarian pada database wajah yang besar.
Penelitian ini dilakukan dengan pendekatan systematic literature Review (SLR), yaitu dengan menggabungkan berbagai sumber dari jurnal penelitian sebelumnya. Tujuan dari penelitian dengan menggunakan pendekatan systematic Literature Review (SLR) ini adalah untuk mengetahui penerapan metode Gabor Wavelet pada Computer Vision.
Hasil dari penelitian ini menunjukkan bahwa penerapan metode Gabor Wavelet pada computer vision banyak digunakan untuk pengenalan wajah (face recognition) dan deteksi wajah (face detection) yang bisa diterapkan di bidang komersial maupun bidang penegakan hukum dengan memberikan hasil yang sangat baik dengan tingkat akurasi 90%.
